Have 5 static IP addresses assigned by Verizon. Appears that ONT is ARPing for the MAC address of the computers that should be assigned the static ip address. My PIX is rejecting these requests because it does not recognize the ONT as a neighboring device. I think the ONT is sending arp as follows: 0.0.0.0 xxxx.xxxx.xxxx <------- (MAC address) Verizon recommends gratuitous arp, but I cannot find anyway to do this in pix. Proxy-Arp is enabled on pix. (I think this is by default.) Does anyone know of a way to get the PIX to send gratuitous arps on behalf of the hosts that will have static IP addresses via static translations? I have a version 6.3 PIX IOS. I also cannot find a way to get the PIX to answer the arp requests. This is probably by design. (Security risk) Would it be possible to put a router configured as a bridge in front of the PIX and use proxy-arp to provide the ONT with the MAC address of the PIX firewall for all the static IP addresses? Is there a better device for this? Any suggestions would be appreciated. | |||||||
